Chapter 19. IWS File/Database Configuration
In this Chapter, we will look at how to configure database connections for Trends, Alarms, Events and the Grid
Object. In subsequent chapters, we will cover the Trending, Alarm, Event and Grid Objects and Worksheets in
further detail.
IWS provides automatic database storage and retrieval for Trend data, Alarms, Events, and the Grid Object.
This data can be stored in either the IWS proprietary database format (to local files), or to a relational
database (local or remotely located) using the built-in ADO.NET interface. The Grid Object can only be used
with the built-in ADO.NET interface (or with Class Objects or Text files).
Using the IWS Proprietary File Format
Trend Data, Alarm Data and Event Data can all be stored (and retrieved) in files on the local computer using the
built-in IWS proprietary format. The advantage of the IWS proprietary database format is that the data is very
compact and a 3 rd party database is not required.
The following chart explains where the database configuration for each Task is located:

• In a Trend Worksheet, select the Proprietary option in the History Format combo
box.
Notes:
• Both the Alarms and Events must be saved in the same format (i.e. IWS Proprietary or to a Relational
Database). If stored to a Relational Database, the Relational Databases can be different
• Each Trend Worksheet can be individually configured to store data in the IWS Proprietary format or to
a Relational Database.
